DETAILED DESCRIPTION

One embodiment of the present disclosure can entail a set top box having a controller to receive a single video stream comprising two-dimensional image content and a depth map of the two-dimensional image content. The controller can generate three-dimensional image content in real-time from the two-dimensional image content and the depth map, where the three-dimensional image content is generated when a display device operably coupled with the set top box is determined to be capable of presenting the three-dimensional image content. The controller can also provide either the two-dimensional image content or the three-dimensional image content to the display device.

One embodiment of the present disclosure can entail a non-transitory computer-readable storage medium operating in a media processor, where the storage medium includes computer instructions to receive two-dimensional image content and a depth map of the two-dimensional image content. The storage medium can include computer instructions to generate three-dimensional image content in real-time from the two-dimensional image content and the depth map. The storage medium can also include computer instruction to provide one of the two-dimensional image content and the three-dimensional image content to a display device.

One embodiment of the present disclosure can entail a method including encoding two-dimensional image content and a depth map of the two-dimensional image content in a single video stream. The method can also include transmitting the single video stream to a media processor for generation of three-dimensional image content in real-time from the two-dimensional image content and the depth map.

FIG. 1 depicts an illustrative embodiment of a first communication system 100 for delivering media content. The communication system 100 can represent an Internet Protocol Television (IPTV) broadcast media system although other media broadcast systems are contemplated by the present disclosures. The IPTV media system can include a super head-end office (SHO) 110 with at least one super headend office server (SHS) 111 which receives media content from satellite and/or terrestrial communication systems. In the present context, media content can represent audio content, moving image content such as videos, still image content, or combinations thereof. The SHS server 111 can forward packets associated with the media content to video head-end servers (VHS) 114 via a network of video head-end offices (VHO) 112 according to a common multicast communication protocol.

The VHS 114 can distribute multimedia broadcast programs via an access network 118 to commercial and/or residential buildings 102 housing a gateway 104 (such as a residential or commercial gateway). The access network 118 can represent a group of digital subscriber line access multiplexers (DSLAMs) located in a central office or a service area interface that provides broadband services over optical links or copper twisted pairs 119 to buildings 102. The gateway 104 can use common communication technology to distribute broadcast signals to media processors 106 such as Set-Top Boxes (STBs) or gaming consoles, which in turn present broadcast channels to media devices 108 such as computers, television sets, managed in some instances by a media controller 107 (such as an infrared or RF remote control, gaming controller, etc.).

The gateway 104, the media processors 106, and media devices 108 can utilize tethered interface technologies (such as coaxial, phone line, or powerline wiring) or can operate over a common wireless access protocol such as Wireless Fidelity (WiFi). With these interfaces, unicast communications can be invoked between the media processors 106 and subsystems of the IPTV media system for services such as video-on-demand (VoD), browsing an electronic programming guide (EPG), or other infrastructure services.

Some of the network elements of the IPTV media system can be coupled to one or more computing devices 130. The computing devices 130, or a portion thereof, can operate as a web server for providing portal services over an Internet Service Provider (ISP) network 132 to wireline media devices 108 or wireless communication devices 116 (e.g., cellular phone, laptop computer, etc.) by way of a wireless access base station 117. The base station 117 can operate according to common wireless access protocols such as WiFi, or cellular communication technologies (such as GSM, CDMA, UMTS, WiMAX, Software Defined Radio or SDR, and so on).

A satellite broadcast television system can be used in place of the IPTV media system. In this embodiment, signals transmitted by a satellite 115 carrying media content can be intercepted by a common satellite dish receiver 131 coupled to the building 102. Modulated signals intercepted by the satellite dish receiver 131 can be transferred to the media processors 106 for decoding and distributing broadcast channels to the media devices 108. The media processors 106 can be equipped with a broadband port to the IP network 132 to enable services such as VoD and EPG described above.

In yet another embodiment, an analog or digital broadcast distribution system such as cable TV system 133 can be used in place of the IPTV media system described above. In this embodiment the cable TV system 133 can provide Internet, telephony, and interactive media services.

It is contemplated that the present disclosure can apply to any present or next generation over-the-air and/or landline media content services system. In one embodiment, an IP Multimedia Subsystem (IMS) network architecture can be utilized to facilitate the combined services of circuit-switched and packet-switched systems in delivering the media content to one or more viewers.

A converter 175 can be used for converting or otherwise adjusting between two-dimensional image content and three-dimensional image content from a depth map of the two-dimensional image content. The image content can be in various forms, including still images, moving images and video games. The converter 175 can be a separate device that is configured for wired and/or wireless communication with media presentation devices and/or media processors, including set top boxes, televisions and so forth. The converter 175 can also be incorporated into the media presentation devices and/or media processors, including the set top boxes and televisions. In one embodiment, the converter 175 can receive a broadcast of two-dimensional image content along with a depth map of the content and can adjust it into three-dimensional image content. In another embodiment the conversion can be performed in real-time, including without the need to change the channel or to interrupt the broadcast. The conversion into three-dimensional image content from the depth map can be based upon various imaging techniques and the three-dimensional presentation can be based upon various formats including polarization, anaglyphics, active shuttering (such as alternate frame sequencing), autostereoscopy, and so forth.

In one embodiment, the computing devices 130 can receive the two-dimensional media content and can generate a depth map therefrom, such as based on object segmentation. In another embodiment, the two-dimensional media content and the depth map can be transmitted from the computing device 130 to the one or more STB's in a single video stream, such as H.264 format encapsulated in an MPEG-2 wrapper.

FIG. 2 depicts an illustrative embodiment of a portal 202 which can operate from the computing devices 130 described earlier of communication system 100 illustrated in FIG. 1. The portal 202 can be used for managing services of communication system 100. The portal 202 can be accessed by a Uniform Resource Locator (URL) with a common Internet browser using an Internet-capable communication device such as those illustrated FIG. 1. The portal 202 can be configured, for example, to access a media processor 106 and services managed thereby such as a Digital Video Recorder (DVR), a VoD catalog, an EPG, a video gaming profile, a personal catalog (such as personal videos, pictures, audio recordings, etc.) stored in the media processor, to provision IMS services described earlier, to provision Internet services, provisioning cellular phone services, and so on.

FIG. 3 depicts an exemplary embodiment of a communication device 300. Communication device 300 can serve in whole or in part as an illustrative embodiment of the communication devices of FIG. 1 and other communication devices described herein. The communication device 300 can comprise a wireline and/or wireless transceiver 302 (herein transceiver 302), a user interface (UI) 304, a power supply 314, a location detector 316, and a controller 306 for managing operations thereof. The transceiver 302 can support short-range or long-range wireless access technologies such as infrared, Bluetooth, WiFi, Digital Enhanced Cordless Telecommunications (DECT), or cellular communication technologies, just to mention a few. Cellular technologies can include, for example, CDMA-1X, UMTS/HSDPA, GSM/GPRS, TDMA/EDGE, EV/DO, WiMAX, SDR, and next generation cellular wireless communication technologies as they arise. The transceiver 302 can also be adapted to support circuit-switched wireline access technologies (such as PSTN), packet-switched wireline access technologies (such as TCPIP, VoIP, etc.), and combinations thereof.

The UI 304 can include a depressible or touch-sensitive keypad 308 with a navigation mechanism such as a roller ball, joystick, mouse, or navigation disk for manipulating operations of the communication device 300. The keypad 308 can be an integral part of a housing assembly of the communication device 300 or an independent device operably coupled thereto by a tethered wireline interface (such as a USB cable) or a wireless interface supporting for example Bluetooth. The keypad 308 can represent a numeric dialing keypad commonly used by phones, and/or a Qwerty keypad with alphanumeric keys. The UI 304 can further include a display 310 such as monochrome or color LCD (Liquid Crystal Display), OLED (Organic Light Emitting Diode) or other suitable display technology for conveying images to an end user of the communication device 300. In an embodiment where the display 310 is touch-sensitive, a portion or all of the keypad 308 can be presented by way of the display 310.

The UI 304 can also include an audio system 312 that utilizes common audio technology for conveying low volume audio (such as audio heard only in the proximity of a human ear) and high volume audio for hands free operation. The audio system 312 can further include a microphone for receiving audible signals from an end user. The audio system 312 can also be used for voice recognition applications. The UI 304 can further include an image sensor 313 such as a charged coupled device (CCD) camera for capturing still or moving images.

The power supply 314 can utilize common power management technologies such as replaceable and rechargeable batteries, supply regulation technologies, and charging system technologies for supplying energy to the components of the communication device 300 to facilitate long-range or short-range portable applications. The location detector 316 can utilize common location technology such as a global positioning system (GPS) receiver for identifying a location of the communication device 300 based on signals generated by a constellation of GPS satellites, thereby facilitating common location services such as navigation.

The communication device 300 can use the transceiver 302 to also determine a proximity to a cellular, WiFi or Bluetooth access point by common power sensing techniques such as utilizing a received signal strength indicator (RSSI) and/or a signal time of arrival (TOA) or time of flight (TOF). The controller 306 can utilize computing technologies such as a microprocessor, a digital signal processor (DSP), and/or a video processor with associated storage memory such as Flash, ROM, RAM, SRAM, DRAM or other storage technologies.

The communication device 300 can be adapted to perform the functions of the media processor 106, the media devices 108, or the portable communication devices 116 of FIG. 1, as well as IMS CDs and PSTN CDs. It will be appreciated that the communication device 300 can also represent other common devices that can operate in communication system 100 of FIG. 1 such as a gaming console and a media player.

FIG. 4 depicts an illustrative embodiment of a presentation device 402 and a media processor 106 for presenting media content. In the present illustration, the presentation device 402 is depicted as a television set. It will be appreciated that the presentation device 402 alternatively can represent a portable communication device such as a cellular phone, a PDA, a computer, or other computing device with the ability to display media content. The media processor 106 can be an STB such as illustrated in FIG. 1, or some other computing device such as a cellular phone, computer, gaming console, or other device that can process and direct the presentation device 402 to emit images associated with media content. It is further noted that the media processor 106 and the presentation device 402 can be an integral unit. For example, a computer or cellular phone having computing and display resources collectively can represent the combination of a presentation device 402 and media processor 106.

The media processor 106 can be adapted to communicate with accessories such as the viewing apparatus 502 of FIG. 5 by way of a wired or wireless interface, including through use of signals 406 from the media processor 106. The communication can be one-way and/or two-way communication, such as providing the viewing apparatus 502 with a transceiver. A wired interface can represent a tethered connection from the viewing apparatus to an electro-mechanical port of the media processor 106 (e.g., USB or proprietary interface). A wireless interface can represent a radio frequency (RF) interface such as the Bluetooth® wireless technology standard, WiFi™ technology, ZigBee® protocols or another wireless standard. The wireless interface can also represent an infrared communication interface. Any standard or proprietary wireless interface between the media processor 106 and the viewing apparatus 502 is contemplated by the presented disclosure.

The viewing apparatus 502 can represent an apparatus for viewing two-dimensional (2D) or three-dimensional (3D) stereoscopic images which can be still or moving images. The viewing apparatus 502 can be an active shutter viewing apparatus. In this embodiment, each lens has a liquid crystal layer which can be darkened or made to be transparent by the application of one or more bias voltages. Each lens 504, 506 can be independently controlled. Accordingly, the darkening of the lenses 504, 506 can alternate, or can be controlled to operate simultaneously.

Each viewing apparatus 502 can include all or portions of the components of the communication device 300 illustrated in FIG. 3. For example, the viewing apparatus 502 can utilize the receiver portion of the transceiver 302 in the form of an infrared receiver depicted by the window 508. Alternatively, the viewing apparatus 502 can function as a two-way communication device, in which case a full infrared transceiver could be utilized to exchange signals between the media processor 106 and the viewing apparatus 502.

The viewing apparatus 502 can utilize a controller 306 to control operations thereof, and a portable power supply (not shown). The viewing apparatus 502 can have portions of the UI 304 of FIG. 3. For example, the viewing apparatus 502 can have a multi-purpose button 512 which can function as a power on/off button and as a channel selection button. A power on/off feature can be implemented by a long-duration depression of button 512 which can toggle from an on state to an off state and vice-versa. Fast depressions of button 512 can be used for channel navigation. Alternatively, two buttons can be added to the viewing apparatus 502 for up/down channel selection, which operate independent of the on/off power button 512. In another embodiment, a thumbwheel can be used for scrolling between channels.

The viewing apparatus 502 can also include an audio system 312 with one or more speakers in the extensions of the housing assembly such as shown by references 516, 520 to produce localized audio 518, 520 near a user's ears. Different portions of the housing assembly can be used to produce mono, stereo, or surround sound effects. Ear cups (not shown) such as those used in headphones can be used by the viewing apparatus 502 (as an accessory or integral component) for a more direct and low-noise audio presentation technique. The volume of sound presented by the speakers 514, 516 can be controlled by a thumbwheel 510 (or up/down buttons—not shown).

It would be evident from the above descriptions that many embodiments of the viewing apparatus 502 are possible, all of which are contemplated by the present disclosure.

FIG. 6 depicts an illustrative embodiment of the presentation device 402 of FIG. 4 with a polarized display. A display can be polarized with well-known polarization filter technology so that alternative horizontal pixel rows can be made to have differing polarizations. For instance, odd horizontal pixels 602 can be polarized for viewing with one polarization filter, while even horizontal pixels 604 can be polarized for viewing with an alternative polarization filter. The viewing apparatus 502 previously described can be adapted to have one lens polarized for odd pixel rows, while the other lens is polarized for viewing even pixel rows. With polarized lenses, the viewing apparatus 502 can present a user a 3D stereoscopic image.

FIG. 7 depicts an illustrative embodiment of a communication system 700 for delivering media content. System 700 can include computing devices 130 for receiving a two-dimensional media content and generating (or otherwise obtaining) a depth map associated with the media content. The computing devices 130 can encode the media content and depth map (such as into a single video stream) and transmit the media content and depth map to one or more media receivers, such as through broadcast, multicast and/or unicast.

In one embodiment, the computing devices 130 can generate the depth map in real-time or near real-time upon receipt of the two-dimensional media content, such as from a broadcast studio. System 700 includes media processors 106 (shown as set top boxes) which receive the video stream of the two-dimensional media content and the depth map. The media processors 106 can generate three-dimensional content using the depth maps in real time upon receipt of the video stream. The media processors 106 can also detect the capability of display devices (such as through HDMI 1.4a) and can adjust the media content accordingly. For instance, if a display device 108 can only present two-dimensional content, then the media processor 106 may discard the depth map and provide the two-dimensional image content to the display device. Otherwise, the media processor can perform the real-time generation of the three-dimensional image content using the depth map and provide the content to the 3D capable display device 108.

FIG. 8 depicts an illustrative embodiment of a method 800 operating in portions of the devices and systems described herein and/or illustrated in FIGS. 1-7. Method 800 can begin with step 802 in which media content in 2D format is received (or otherwise obtained) by a service provider, such as computing devices 130. The media content can be of various types including still images, moving images and video games. In step 804, the computing devices 130 can generate (or otherwise obtain) a depth map of the two-dimensional image content. The particular components and techniques utilized for generating the depth map can vary and can include object segmentation. In one embodiment, the depth map can be generated in real-time as the two-dimensional media content is being received from a media source, such as a broadcast studio.

In step 806, the two-dimensional media content and the depth map can be transmitted to one or more media processors, such as through broadcast, multicast, and/or unicast. In one embodiment, the two-dimensional media content and the depth map can be packaged in a single video stream, such as through MPEG-2 encapsulation. In one embodiment, the video stream can essentially consist of the two-dimensional media content and the depth map so that bandwidth is conserved. For instance, the depth map can be depth data rather than depth-adjusted images, and then later the depth data can be utilized for generating the depth-adjusted images.

In step 808, the capability of the display device(s) to present three-dimensional content can be determined. For instance, each of the media processors (such as STB's) can detect without user intervention whether a display device operably coupled to the STB can receive and present three-dimensional content. The exemplary embodiments contemplate other techniques for determining the capability of the display device to present the content, including detecting the availability of a viewing apparatus that would be necessary to view the three-dimensional content, as well as presenting an option to a viewer for selection of the type of content.

In step 810, if the display device is incapable of presenting three-dimensional content then the depth map can be discarded or otherwise ignored by the STB and the two-dimensional content can be presented by the display device in step 814.

If on the other hand the display device is capable of presenting three-dimensional content and such a presentation is desired then in step 812 the media processor (such as the STB's) can generate three-dimensional content utilizing the depth map and the two dimensional content. For instance, the STB's can generate image pairs using the depth map, such as the two dimensional content image being the left pairing and the depth-adjusted image being the right pairing. The left and right pairings can then be sequentially presented at the display device and viewed utilizing active shutter glasses. In another embodiment, the left and right pairings can be generated as described above and then combined but oppositely polarized and viewed utilizing polarized glasses. The exemplary embodiments contemplate other techniques for generating the three-dimensional content from the two-dimensional content and the depth map.

The particular methodology employed to provide or render the three-dimensional image content can vary and can include active shutter (alternate frame sequencing), polarization and other techniques. The 2D media content and depth map can be received by the media processor from various sources, such as via a broadcast over an IPTV network, cable, DBS and so forth.

The exemplary embodiments contemplate a viewing apparatus (such as active shutter glasses or passive polarization glasses) being detected through various means. The detection can be performed by the media processor, although other devices can also be utilized for this purpose as well. The detection can be based upon a number of thresholds, including recognizing that a viewer is wearing the viewing apparatus; detecting that the viewing apparatus is in a line of sight with a display device upon which the media content is or will be displayed; and determining that the viewing apparatus is within a pre-determined distance of the display device. The techniques and components utilized for detecting the viewing apparatus can vary. For example, the media processor can scan for the presence of the viewing apparatus. This can include two-way communication between the media processor and the viewing apparatus. In one embodiment, the viewing apparatus can emit a signal which is detected by the media processor. Presence and/or distance can be determined based on the signal, including utilizing signal strength. Location techniques can also be used for determining a position of the viewing apparatus, including triangulation and so forth.

In one embodiment, 2D HD video with standard encoding/compression techniques can be utilized for the method 800. At the receiving end, standard decoders can also be utilized in conjunction with the depth map where three-dimensional image content is desired.

Upon reviewing the aforementioned embodiments, it would be evident to an artisan with ordinary skill in the art that said embodiments can be modified, reduced, or enhanced without departing from the scope and spirit of the claims described below. The embodiments described above can be adapted to operate with any device capable of performing in whole or in part the steps described for method 800. For example, a cellular phone can be adapted to convert a broadcast of 2D image content to 3D image content using a received depth map.

In one embodiment, both the generation of the depth map and the conversion from 2D to 3D format can be performed in real-time by the back-end server and the STB, respectively, so that a broadcast is not interrupted. In another embodiment, the media content can be video games that are being transmitted to a gaming console in 2D format, such as from a backend server over the Internet. The gaming console can then selectively convert the 2D images to 3D images for presentation on a display device, such as a television or a monitor.

In one embodiment, the media processor can be a gateway connected with each of the STBs or connected directly with the display devices. The exemplary embodiments also contemplate a residence or other location where a portion of the display devices are presenting three-dimensional content and another portion of the display devices are presenting two-dimensional content. In one embodiment, the generation of the three-dimensional content can be performed by a single media processor and distributed to other media processors to avoid duplication of processing. In another embodiment, the generation of the three-dimensional content can be done in a distributed fashion using multiple media processors at the residence or other location, to generate the three-dimensional content for select portions of the content. In another embodiment, the media processor can detect whether the incoming video stream has a depth map.

The depth map can be generated directly from the two-dimensional images and/or can be generated using metadata that accompanies the two-dimensional image content, such as in the single video stream. In one embodiment, the depth chart is generated for select objects shown in the two-dimensional image content.

Other suitable modifications can be applied to the present disclosure without departing from the scope of the claims below. Accordingly, the reader is directed to the claims section for a fuller understanding of the breadth and scope of the present disclosure.
